Introduction

This service manual contains
detailed descriptions of all the repair
and servicing procedures specific to
this series of chain saws.
There are separate handbooks for
servicing procedures on
standardized parts and assemblies
that are installed in several STIHL
power tool models. Reference is
made to these handbooks in the
appropriate chapters of this manual
You should make use of the
illustrated parts lists while carrying
out repair work. They show the
installed positions of the individual
components and assemblies.
Refer to the latest edition of the
relevant parts list to check the part
numbers or any replacement parts.
Parts lists on microfiche and CD-
ROM are always more up to date
than printed lists.
A fault on the machine may have
several causes. To help locate the
fault, consult the troubleshooting
charts for all assemblies in the
"Standard Repairs, Trouble-
shooting" handbook.
Refer to the "Technical Information"
bulletins for engineering changes
which have been introduced since
publication of this service manual.
Technical information bulletins also
supplement the parts list until a
revised edition is issued.

Service manuals and all technical
Information bulletins are intended
exclusively for the use of STIHL
servicing dealers. They must not be
passed to third parties.
Servicing and repairs are made
considerably easier if the
powerhead is mounted on assembly
stand (1) 5910 890 3100. Remove
the chain sprocket cover, bar and
chain first.
The powerhead can then be
swivelled to the best position for the
ongoing repair. This leaves both
hands free.
Always use original STIHL
replacement parts.
They can be identified by the
STIHL part number,
the 67,+ logo and the
STIHL parts symbol
This symbol may appear alone on
small parts.
